Alright,
I've just pushed up support for variables. The following should all
work as expected (or at least as I would expect them to). Note that
most all of these blocks would have an effect on the calc stack. I
think the next step would be to allow different sessions to specify
different stacks.
** playing with calc support
#+begin_src emacs-lisp :results silent
(require 'ob-calc)
#+end_src
#+begin_src calc :var some=8
some
some
'*
1
'+
#+end_src
#+results:
: 65
#+begin_src calc
2*(8+8)
#+end_src
#+results:
: 32
#+begin_src calc
2*e
#+end_src
#+results:
: 5.43656365692
#+begin_src calc :var something=9
2*something
#+end_src
#+results:
: 18
There are very likely some bugs, and as always I'm eager for a calc
power user to show me the light of how this support could be make more
"calc idiomatic".
Cheers -- Eric
